  • Patent number: 5393446
    Abstract: A detergent composition comprises a fired ceramic body, which carries as effective ingredients sodium oxide and potassium oxide thereon. Sodium metaphosphate and/or calcium oxide may also be carried as optional ingredient(s). The fired ceramic body may be made of a ceramic material formed primarily of silicon oxide and aluminum oxide. Preferably, the detergent composition may be in the form of granules and may be enclosed in a container defining apertures through a wall thereof. These apertures are dimensioned so that the granular detergent composition are prevented from being lost therethrough. A granular detergent composition can be produced, for example, by adding sodium oxide and potassium oxide to a ceramic material, adding water to the resulting dry ceramic powder, kneading and forming the resulting mixture into a green body of a predetermined shape, drying the green body, firing the thus-dried green body at 500.degree. C. to 700.degree. C.
